Abstract : This report summarizes research conducted by S-Cubed to develop advance constitutive models of plain and reinforced concrete for ultimate use in the cost-effective design and hardness assessment fo concrete protective structures. The specific goals of the research are: (1) developement of a mixture theory which can accurately account for steel-concrete interaction and (2) formulation of an advanced constitutive theory for plain concrete which can accurately portray its nonlinear, inelastic behavior including damage and microcracking for arbitrary loading histories. The importance of the steel-concrete interaction and the nonlinear inelastic behavior of the palin concrete, including cracking, is emphasized. Keywords: Concrete failure modes; Continuous damage model; Dowel action; Evolution equation; Endochronic theory.
